My plan with my JB700 is to blow the vapor in the 1" holes bored in the face of my hive bodies as my entrances are only 1/4" deep. I took the straight pipe I received with my machine to the hardware store and found a 1 1/2 threaded by 1"barb grey plastic fitting. The screw portion indeed screws inside the 2" straight piece. I plan to taper the barb with my grinder so it fits just a tad less snugly in the holes in my boxes. Now if the respirator would arrive or if I could find the ones I used regularly a dozen years ago turn up--I could get to work killing mites.
